Abstract

In recent years the emergence of membrane-type acoustic metamaterial which has been a subject of widely-extended discussion provides a novel way to isolate the low-frequency noise In this study I fabricated a novel structure called coupled membrane structure which is comprised of two membrane-type metamaterials I used the acoustic impedance tube and Comsol Multiphysics a finite element analysis software package to examine its transmission loss (TL) Compared to the single-layer metamaterial an extra TL peak and valley are occurred I also discovered that the effect of the thermal-curing temperature and air spacing on the TL curves A good agreement between experiment and simulation is achieved
